Alien Nation,
which ran for one season from 1989 to 1990 on Fox, was a sci-fi drama spun
off from the 1988 movie called Alien Nation.
TV Guide listed the series as one of the 60 shows that
were cancelled too soon. The show was continued
into the 1990's with a number of made for TV movies that
featured the original cast. In the show, Detective
Sikes was played by Gary Graham, and Detective Fancisco
by Eric Pierpoint.

In this
show, an alien slave ship crashed in the desert.
The aliens, or "newcomers" as they were called, were
eventually assimilated into the general population of
Los Angeles. One of them, George Francisco (Pierpoint), paired
up with a human cop, Matthew Sikes (Graham), to fight both crime
and prejudice as they both learned to appreciate each
other's culture. Racism and bigotry were
significant themes throughout the series, as long as the
occasional weird thing, such as the fact that the male
aliens were the ones who bore their young.
